Grin released their REAR All-Axle Hub Motor

Feature highlights:

• Thru-axle and QR compatible
• Built-in torque arm
• 11-speed cassettes
• Integrated cadence PAS sensor
• Made in Canada

Sadly it didn't get a torque PAS sensor.

If you're in the market for an electric conversion kit and you like the idea of direct-drive hubs, it probably doesn't get better than this.
